通过施加压应力诱导的 Ni2MnGa 中 X 相的中子衍射剖面表明，在约 30 MPa 的压应力下，在 240 K 温度下，在 [h2 - h0](p)* 的不公度位置出现了两个卫星反射，其中 h = 0.360 和 1.638。 X相的卫星位置与马氏体和中间相的卫星位置明显不同。 (C) 2008 Acta Materialia Inc. 由 Elsevier Ltd 出版。保留所有权利。
Neutron diffraction profiles of the X-phase in Ni2MnGa, which is induced by applying a compressive stress, have revealed that two satellite reflections appear at incommensurate positions of [h2 - h0](p)*, with h = 0.360 and 1.638 at 240 K under a compressive stress of about 30 MPa. The satellite positions of the X-phase are clearly different from those of the martensite and intermediate phases. (C) 2008 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
